Foundation Piering & Settlement Repair in Chicago
Our team at Perma-Seal offers professional foundation piering services to repair foundation settlement problems for Chicago and NW Indiana home and business owners.
Foundation Settlement Piering
When a foundation begins to settle, the problem often starts with small warning signs. Cracks appear in the brickwork. Doors and windows become harder to open. Floors begin to slope. Over time, those symptoms can worsen as portions of the foundation lose support from the soil beneath them.
At Perma-Seal, we’ve spent more than 45 years helping homeowners throughout Chicago, the surrounding suburbs, and Northwest Indiana stabilize settling foundations using proven foundation piering systems. Whether you’re dealing with a sinking foundation, settlement cracks, or structural movement, our team can determine whether foundation piers are the right solution for your home.
When Are Foundation Piers Needed?
Foundation piers are typically recommended when a foundation has settled or continues to settle because the soil beneath it can no longer adequately support the weight of the structure.
Many homeowners first contact us after noticing:
- Stair-step cracks in brick or masonry
- Cracks in foundation walls
- Uneven or sloping floors
- Doors and windows that stick
- Gaps around windows, trim, or baseboards
- Chimneys separating from the home
- Portions of the foundation appearing to sink
One of the most common misconceptions we encounter is the belief that settlement has stopped simply because cracks haven’t changed recently. In reality, foundation movement can continue gradually over time.
Why Foundations Settle in Chicagoland
The soil conditions throughout Northern Illinois play a major role in foundation settlement. Many homes throughout Chicago and the surrounding suburbs are built on clay-rich soils. These soils expand when wet and contract when dry. Over time, these cycles can create voids beneath portions of a foundation, reducing support and allowing settlement to occur.
Our inspectors commonly find settlement associated with:
- Expansive clay soils
- Seasonal moisture changes
- Extended wet or dry periods
- Soil erosion
- Poor drainage around the foundation
- Improperly compacted fill soils
Settlement often develops gradually. What starts as a small crack may eventually become uneven floors, wall movement, or more significant structural concerns if the underlying issue is not addressed.
How Foundation Piering Works
Foundation piering is designed to stabilize foundations by transferring the weight of the structure from unstable soils near the surface to deeper, load-bearing soils or bedrock.
The process generally includes:
- Excavating around the affected portion of the foundation.
- Installing engineered foundation brackets.
- Advancing steel piers into the ground until stable load-bearing material is reached.
- Transferring the weight of the structure onto the pier system.
- Stabilizing the foundation to help prevent further settlement.
In many situations, portions of the structure may also be lifted closer to their original positions, though the amount of lift varies depending on the home’s condition and the extent of settlement. The goal is not simply to raise the home. The primary goal is to stop further movement and restore long-term structural support.
Push Piers vs. Helical Piers
Not every settlement problem requires the same repair solution. At Perma-Seal, we use both push piers and helical piers based on the project’s structural requirements, soil conditions, and foundation design.
Push Piers
Push piers are hydraulically driven steel piers that use the weight of the structure as resistance during installation. They are one of the most common settlement repair solutions we install throughout Chicagoland. These systems are commonly used when:
- Significant structural loads are present
- Settlement has already occurred
- Deep load-bearing soils are required
- Foundation lifting may be possible
Helical Piers
Helical piers resemble large steel screws that are rotated into the ground until stable soil conditions are reached.
Helical piers are often used when:
- Structural loads are lighter
- Access conditions vary
- New construction support is needed
- Soil conditions favor helical installation
Do All Settlement Cracks Require Foundation Piers?
No. Not every foundation crack indicates a need for structural stabilization. Some cracks are cosmetic. Others may be related to normal concrete shrinkage, isolated waterproofing concerns, or minor movement that does not require piering. Click here to learn about the types of foundation cracks. During our inspections, we evaluate:
• Crack patterns
• Structural movement
• Settlement indicators
• Foundation elevation changes
• Soil conditions around the structure
Settlement often develops gradually. What starts as a small crack may eventually become uneven floors, wall movement, or more significant structural concerns if the underlying issue is not addressed.

Frequently Asked Questions
What causes foundation settlement in Chicago-area homes?
Foundation settlement in Chicago and NW Indiana is commonly caused by shifting soils, excessive moisture, poor drainage, or soil erosion beneath the foundation. Expansive clay soils, common throughout the Chicagoland area, expand when wet and shrink when dry, causing movement that can sink or settle foundations over time. Foundation piering addresses these issues by transferring the structure’s weight to stable, load-bearing soil or bedrock.
How do foundation piers fix a settling foundation?
Foundation piers stabilize a settling foundation by bypassing weak or unstable surface soil and anchoring the structure to deeper, competent soil or bedrock. At Perma-Seal, steel push piers or helical piers are installed below the foundation and hydraulically driven or screwed into the ground. Once secure, the weight of the home is transferred to the piers, preventing further settlement and, in many cases, allowing the foundation to be lifted closer to its original level.
What is the difference between push piers and helical piers?
Push piers are hydraulically driven steel piers that rely on the structure’s weight to reach load-bearing soil or bedrock, making them ideal for heavier homes with significant settlement. Helical piers are screwed into the ground and are often used in areas with weaker soils or where access and load requirements differ. Perma-Seal determines the optimal pier type based on soil conditions, foundation design, and settlement severity.
Is foundation piering a permanent solution for settlement problems?
Yes. Foundation piering is considered one of the most permanent solutions for foundation settlement. Unlike temporary fixes such as mudjacking or slabjacking, piering systems are designed to provide long-term structural support by anchoring the foundation to stable soil. When properly installed by experienced professionals like Perma-Seal, foundation piers help prevent future settlement and protect your home’s structural integrity.
How do I know if my Chicago home needs foundation piering?
Common signs that your home may need foundation piering include stair-step cracks in brick or block walls, uneven or sloping floors, sticking doors or windows, and visible foundation settlement. If you notice these issues, it’s important to schedule a professional foundation inspection. Perma-Seal offers expert evaluations throughout Chicago and NW Indiana to determine whether foundation piering is the right solution for your property.
